3.Configure Voice/Fax Parameters.

3a. In the MultiVOIP’s Configuration Voice/Fax Parameters screen, configure the voice channels for a voice coder that is supported by Communication Manager.

The voice coder selected must match the voice coders listed in the ip-codec-set for the network region the MultiVOIP resides in. If only G.729 is listed in the ip-codec-set, select G.729 on the MultiVOIP. If G.711 is listed before G.729 in the ip-codec-set, select G.711, G.729 on the MultiVOIP. If G729 is listed before G.711 in the ip-codec-set, select G.729, G.711 on the MultiVOIP.

There is one exception, if only G.711 is listed in the ip-codec-set, you must select G.711, G.729 on the MultiVOIP. This will allow support for G.711 for CM managed calls, and will allow support for G.729 for survivable mode calls. The MultiVOIP only supports G.729 in survivable mode.

The table below shows the bandwidth required per voice channel based on the codec selected and the CM “Frames per Packet” setting in the “Change IP-Codec-Set” screen.

Bandwidth per Channel

Voice Frames per IP Packet

Coder	1	2	3	4

G.729	40K bps	24K bps	18K bps	16K bps

G.711	96K bps	80K bps	74.7K bps	72K bps

3b. If the CM customer desires that a particular FXS port is to operate as a “hot extension”, set the “auto call/off-hook alerting” feature to auto call and enter the desired destination number in the “phone number” field. Enabling this feature allows an analog phone user to be able to lift his/her
